Abstract

We are interested in peer-to-peer (P2P) computing, where a P2P application consists of a (wireless) network of nodes (peers), and assumes full peer autonomy, no global control, and intermittent connectivity. P2P computing has many advantages over classical client-server and web-based distributed architectures. However, the P2P computing model also has a number of limitations in the mechanisms it supports for data management and interchange. To overcome some of these, we propose an agent-based P2P model whose nodes are software agents (peer agents). This paper uses the i* modeling framework to analyze and evaluate peer agent cooperation strategies using three possible evaluation criteria.
